How chameleon changes colours
In: Biology
A chameleons skin is transparent at its outermost layer, beneath this are multiple layers of cells called chromatophores. These chromatophores have little sacs filled with different pigments and are responsible for different colors.
As for how it uses them, its nervous system activates them so that different colors are shown due to different stimuli. A chameleon that’s excited for example will use its red colors while a calm one will turn green and maybe a bit of blue.
